.'l'o all whom it may concern: y y

Be it known that LlJoHN MILTON GURTICE, a citizen of the United States, `residing at Lowell, in the county of Middlesex and `State of Massachusetts, have invented certain new and l useful lmprovementsin Bobbin-Holders for Spooling-Machincs; andlI do hereby declare the following to be a full, clear, andexact description of' the invention, such as will enable 1o others skilled in the art to which `it appertains to make and use the same, reference beinghad to the accompanying; drawings, and to `letters or `figures of' reference marked thereon, which l form a part of this specification.

y 1 5` `Myinvention consists, primarily, in the combination, with a stationary cradle designed to support the bobbin, ot' a rockin gshield or hood f pivoted at one end.` to vone end of the cradle,

and adapted to more in the arc ot' a circlepartially'about the said` cradle, for the double p'urg pose of exerting its weight upon theyarn to produce altension upon the latter, and to partially cover the cradle and bobbin` and prevent escape of the latter when thethread-is intact, and toi'all awayio oneI sideof the said `cradle upon breakage or running ont ot' a thread, in order that no obstructionmay be,

presented to bar ready access to the bobbin. My improvements further consist in'provid- `3pc-ring the cradle with an adjustable'endpiece,

whereby the effective length of the said cral dle may be varied to ,accommodate bohbins ot' various lengths. y

My improvements further consist in the einployment ot a horn upon the outer end of the rocking shield, this horn being inclined away from the body of the shield, and standing in such position relative to the adjacentend ot' the cradle as to enable the yarn from the bobf bin to be readily and instantly passed beneath `y* .the shield.

l represents a plan viewof a bobbin-hlder em` `In the accompanying drawings, Figure b odying my invention. Fig. 2`represents a longitudinal vertical section of the saine. Fig. 3 represents a transverse vertical section of the same, showing a modification of the devices for` adjusting tension. Fig. 4 represents an end view of abobbin-holder similar to that l `5c shown in Fig. l, the shield being turned so as y 1 y to entirely uncover the bobbin; and Fig. 5

represents a perspective view, o n a largerscale, ot' a bobbin-holder similar to that shown in Fig. l, showing the hobbin a little displaced.

I Reference being had to the above-men tioned drawings, A designates a bobbin-holder, consisting, principally,l ofa straight,semi-tubular cradle, B, for the bobbin. When spooling a Woof-thread the holder stands nearly perpendicular, but while spooling a Vwarp-thread the holder is horizontal, as shown in the drawings. The holder A is provided with the usual lateral pivot, (l, by which it is supported in position. Theouter end or nose, D, of the tubu` lar cradle B vis contracted to support the small end of the bobbin and raise the yarn upon the latter above the floor of the cradle. The inner end otl the cradle B is formed with a tubular axle, a. `The hub b of shield E loosely surrounds'tiiisaxle. This shield is outside ot the cradle and cap-able of rocking motion about the cradle, between two extrelnes of movement, in oneol' which `it lies idle along` side such cradle, with its upper edge .about Von a level with the adjacent edge ofthe cradle,

while in the other extremeit extendsabove the latter edge and partially covers the cradle. In the iirst-named position the ,shield is idle and falls away from over the cradle, to permit of ready insertion orremovalot' a bobbin,while y in thelatter position itconstitutesa cover to the cradle, to prevent the bobbiu fromjumping out.

When the shield is in an intermediate position the thread passes out from the bobbin throughl the opening between the edges of the cradle and shield on one side of said cradle, and is in contact with the lower edge of said shield. The huh b of said shield has a weight attached to it on the side opposite to that ou which the thread passes out of said bobbin-holder. Said weight eounterhalances said shield to a degree depending on theleverage exerted bysaid weight, and preferably consists, as shown in the drawings,of a screw,c,havinga large head and screwing into or out of said hub radially, to vary the leverage exerted by the gravity ot' itshead. Byadvancingorretractingthescrew c the shield is counterbalanced to a greater or less extent, and the weight and tensionexerted by it upon the thread proportionately increased or diminished.

roo

Ido not conline myself to the adjustable weight c as a means of varying the pressure ofthe shield upon the thread, as various other devices may be employed for the purpose.

To adapt the cradle for holding bobbins of 5 various lengths, I provide it at one end with a fiat head or end plate, d, having a shank, c, which is inclosed in a socket, j', formed in the tubular axle a ot' the cradle, and is confined within such socket by a clamp-screw, g, inio serted in one side ot' the said axle and intercepting the shank e.

v The outer end of the shield E is tapering and terminates in a horn, h, which departs at atangent from thecircumferenceof the cradle,

i5 as shown particularly in Fig. 1 ot the drawings. The purpose ot' this horn is to enable the bobbin-thread to be readily inserted or passed beneath the shield, when a full bobbin is substituted for an empty one or when a 2o thread is tied after breaking.

vln the use ot' my holder, above described, supposing the cradle to be empty, with its shield dropped to the lowest point on one side of such cradle, as shown in Fignt ofthe drawings, a full bobbin is placed in it from above, this act being accomplished with the greatest 4 ease, as the top of the cradle is entirely unob- "structed. The bobbin-thread is then passed about and beneath the horn h and led under 3o the body of the shield E, and thence upward through the thread-guide of the spooling-machine. The draft upon the thread in the act of spooling tightens such thread to such a de gree as'to cause it to lit't and support the weight ot' the shield E, from which it derives a certain degree of tension, which is of great advantage. The lifting vof the'shield by the draft upon the thread,as stated,also serves to cover theicradle and prevent the bobbin from 40 jumping out should a thread break, the shield dropping to its lowest point, and the operator being enabled to readily pick up and tie the ends, after which the thread is again passed beneath the shield, as above stated.

It will be seen that the shield operates au tomatically to uncover the cradle, and, when the bobbin-thread breaks or runs out, permits of ready access to the cradle for the purposey of removing the empty bobbin and substituting a full one, while the draft upon the thread from the lled bobbin also operates automatically to lift the shield and cover the cradle. The adjustable end plate is an inexpensive and effective means of varying the et't'ective length ot' the cradle. 55 In the modification shown in Fig. 3 the weight is a nut marked b', and screws upon the screw-threaded outer end of a bent rod, a',

which is attached to the hub of shield E. The

point of attachment corresponds to that of 6o screw o in Fig. 1, and' the operation thereto. Whenever the outer end ot' rod a is inclined the adjustment ot' tension may be effected by screwing the nut b up or down on said rod.

Having thus explained the nature,purpose, and operation of my invention,I claim and desire to secure by Letters Patent the following;

l. A .bobbin-holding cradle, in combination with a shield adapted to rock thereon from side to side, said shield being weighted to diminish tension on the thread passing from the bobbin, as set forth.

2.v A bobbin-holding cradle provided with an axle at one end thereof, in combination with al shield which has a tubular hub turning on said axle, substantially as set forth.

3. The combination, with a bobbin-holding cradle, ot' a longitudinally-adjustable end plate for adapting said cradle to bobbins of various sizes, substantially as set forth. 4. The combination, with cradle B, of the rocking shield E,provided at one end with the inclined horn h, substantially 'as and for the purpose set forth.

In testimony whereotl I aftix my signature in presence of two witnesses.

JOHN MILTON GURTICE.
